Owner’s Manual and Service Guide
Read all of manual to become thoroughly familiar with this vehicle. Pay particular attention to all Notes, Cautions and Warnings
Even if the water is colorless, odorless, tasteless and fit
for drinking, the water should be analyzed to see that it
does not exceed the impurity levels specified in the table.
Automatic watering devices such as the one included in
the Battery Maintenance Kit (P/N 25587-G01) can be
used with an approved water source (Ref. Fig. 28 on
page 21). These watering devices are fast and accurate
to use and maintain the correct electrolyte level within the
battery cells.
The watering device should only be used if the
electrolyte level is less than 1/2" (13 mm)
above top of plates.
BATTERY CLEANING
To prevent battery damage, be sure that
all battery caps (if equipped) are tightly
installed.
To reduce the possibility of damage to vehicle or floor, neutral-
ize acid before rinsing battery.
To reduce the possibility of damage to electrical components
while cleaning, do not use a pressure washer.
Cleaning should take place per the Periodic Service
Schedule (Ref. Fig. 20 on page 15).
When cleaning the outside of batteries and terminals,
first spray with a solution of sodium bicarbonate (baking
soda) and water to neutralize any acid deposits before
rinsing with clear water.
Use of a water hose without first neutralizing any acid will
move acid from the top of batteries to another area of the
vehicle or storage facility where it will attack the metal
structure or the concrete/asphalt floor. Additionally, con-
ductive residue will remain on the batteries and contrib-
ute to their self discharge.
To reduce the possibility
of battery explosion that
could result in severe
injury or death, do not use metallic spray wand to
clean battery and keep all smoking materials, open
flame or sparks away from the battery.
The correct cleaning technique is to spray the top and
sides of the batteries with a solution of sodium bicarbon-
ate (baking soda) and water. This solution is best applied
with a garden type sprayer equipped with a non metallic
spray wand or plastic spray bottle. The solution
should consist of the ingredients shown in the illustration
(Ref. Fig. 29 on page 22). In addition, special attention
should be paid to metal components adjacent to the bat-
Allow the solution to sit for at least three minutes. Use a
soft bristle brush or cloth to wipe the tops of the batteries
to remove any conductive residue. Rinse the entire area
with low pressure clear water. Do not use a pressure
washer. All of the items required for complete battery
cleaning and watering (electric vehicles only) are con-
tained in the Battery Maintenance Kit (P/N 25587-G01).
BATTERY REPLACEMENT
Remove battery hold downs and cables. Lift out batteries
with a commercially available lifting device.
If the batteries have been cleaned and any acid in the
battery rack area neutralized as recommended, no corro-
sion to the battery racks or surrounding area should be
present. Any corrosion found should be immediately
removed with a putty knife and a wire brush. The area
should be washed with a solution of sodium bicarbonate
(baking soda) and water and thoroughly dried before
priming and painting with a corrosion resistant paint.
The batteries should be placed into the battery racks and
the battery hold downs tightened to 45 - 55 in. lbs. (5 - 6
Nm) torque, to prevent movement but not tight enough to
cause distortion of the battery cases.
Inspect all wires and terminals. Clean any corrosion from
the battery terminals or the wire terminals with a solution
of sodium bicarbonate (baking soda) and brush clean if
required.
